Y Application filed September 7, 1900. Serial No. 29,273. (No model.)

[o all whom/ it m/ty concern.-

Be it known Ithat LGEORGE l-I. LARKIN, a citizen of the United States, residing in the city and county of San Francisco, in the State of California, have invented an Improvement in Hydrocarbon-Burners; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to improvements in hydrocarbon-burners.

It consists of peculiarly-curved Wires held centrally within the burner tube or casing and extending into the discharge-passage, peripheral wire extensions upon the interior of the discharge-tube, Y an oil-inlet feeding centrally into the burner and upon the firstnamed wires and means for regulating'the oil-supply and the blast, and of details more fully to be set forth in the following specification and drawings, in which-- Figure l is a longitudinal vertical section through the burner. Fig. 2 is a front end view of the same.

A represents the casing.

B is a radial nipple carrying on its outer end the feed-cock D. A washer 2 is interposed between the parts to make a tight joint. On the lower or inner end of'B is the T C, so disposed as to bring the axis of the longitudinal opening of C in line with the similar axis of A. Within C is the bolt E, having a conical head 3, adapted to bear against the ends of the wires F, which are inserted in the annular opening between 3 and C, and to lock them and make an oiltight joint when the nut 4 on the other end of E is tightened against the plate 5, fitting over the end of C. A washer 6 is interposed between 5 and C to insure a tight joint.

The discharge or burner tube G is secured in A. This discharge tube is made with numbers of interior projections, one form of which is represented by the wires shown in Fig. l. I have shown these projections as wires H, converging inwardly from the casing A and terminating short of the line of the axis of G. The wires F extend into the tube G and are looped or curved at 7 and have their ends 8 terminating near the axial line of G.

The T C has aperforation 9, through which oil is fed centrallyinto the burner-casing and upon the wires F. Air or steam, or both, may be injected with the oil. i

K is a gate by which this blast is regulated.

The advantages of my burner are seen in its operation.

First. Oil is fed through D, B, and 9 int-o' the central portionof the burner substantially in line with`the air or like blast. The blast is thereby not deflected, acts with more force upon the flowing oil, and tends to better atoniize and distributeY it.

Second. The wires F assist, further, in the breaking up of the drops of oil in its more perfect vaporization, and by the termination of the ends of these wires centrally of the discharge-tube and preferably in the direction of the blast the oil is led toward the center and stronger part of the blast' and not left to owon along the wall of the dischargetube.

Third.` The projections or pins H, which also preferably extend in the direction of the blast, play an important part as auxiliary atomizers.

Ordinarily much oil drops upon the lower part of the tube, and in fact on the whole inner surface of the tube, and is carried on into the furnace without being properly vaporized. The object of these pins or projections is to interrupt continually this ow and to act as ducts to lead the oil back again into the center of the blast. The object of curving the wires F byturning their ends inward and in the direction of the air-blast is to let the wires not terminate against the wall, whereby they would continually lead the oil from the vcenter to the wall when the reverse is desirable. By these devices I secure practically absolute and perfect vaporization.

It will be manifest that either air or steam may be used separately or both in unison, the object being in any case to disperse the oil and provide for a complete combustion. The inlet tube or nipple Bis inclosed in a radial tubular casing a, which may be formed with or secured to the interior of the part A. The tube B is thus protected from the wearing impact of the blast.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A hydrocarbon burner, comprising a Ioo casing having an air-blast inlet and a discharge tube, an oil -feeder discharging into the blast, and a series of rods leading from the discharge-tube and having their outer ends turned inwardly toward each other and away from the inner Walls of the casing.

2. A hydrocarbonburner comprising a casing havingablastinlet and discharge tube horizontally in line, an oil-supply pipe entering the casing at right angles to the line of the blast, said oil-pipe having an opening within the casing for the admission of oil to the burner, and a tubular series of rods,-\vhich latterextend into the discharge-tube, and are so ared that their ends lie in the direction of the blast and toward the center of the tube.

3. A hydrocarbon-burner comprising a casing having a blast-inlet, and oppositely thereto a discharge-tube, a nipple in this casing placed vertically to the line of the blast, a T on the lower end of this nipple, said T placed centrally of the interior of the casing, and having its longitudinal opening in the axial line of the dischargetube, a shaft through this opening of the T having a flared end adapted to hold the ends of a tubular series of ared Wires or rods within the T, and said shaft having means of adjustment atits other end, an oil-outlet in the T above the Wire connection, and on the side toward the discharge-tube, said fiared Wires extending into the discharge-tube, and their ends terminating near the axial line of the tube.

et. A hydrocarbon-burner comprising a casing, having a longitudinal inlet blast-pipe and discharge-pipe, a vertical oil-feeder entering the casing and discharging centrally thereof, a tubular series of Wires extending into the discharge-pipe, one end of these wires attached at the lower end of said feeder, the other end of the Wires turning towa\rd the axial line of the discharge-tube, and in the direction of the blast, and aseries of peripheral projections Within the discharge-tube.

5. The combination in a hydrocarbonburner with a casing having a discharge-tube, of an air-blast inlet, and means for regulating the blast, said air-blast inletin line with the discharge-tube, an oil-feeder with means for regulating the supply of oil, said oil-feeder entering the casing at right angles to the line of the blast, and discharging centrally of the casing and upon wires secured within the part of the feederinclosed by the casing, said wires extending into the discharge-tube and having a loop intermediate of their ends and the ends of these wires terminating near the axial line of the tube, and of peripheral projections within the tube, extendingin the direction of the discharge end of the tube-and terminating near the axial line of the tube.

6. The combination with the dischargepassage of ahydrocarbon-burnerof divergent wires disposed about the axis of the passage. said wires having their outer ends curved toward lthe axis.

7. In a hydrocarbon-burner, a casing having an inwardly-projecting radial sleeve, au oil-inlet tube inclosed thereby, a receiving and delivery T upon the inner end of the inlet-tube and abutting against the inner end of the sleeve, a series of annularly-disposed wires fixed in said T, diverging outwardly therefrom into the dischargepassage, and having their outer ends returning toward the axis of said passage.

In witness whereof I have hereunto set my hand.
